IMPROVEMENT IN SEWING-MACHINE TABLES.

Specification forming part of Letters Patent No. 122,872, dated January16, 1872.

To all whom it may concern:

Be it known that I, AUSBERT H. WAGNER, of Chicago, in the county of Cookand in the State of Illinois, have invented certain new and usefulImprovements in Sewing-Machine Tables 5 and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing making a part of thisspecification, in which- Figure 1 is a perspective view of my device.Figs. 2 and 3 are, respectively, a front and an end elevation of thesame. Fig. 4 shows said device as closed together for transportation orstorage; and Fig. 5 is an enlarged rear view of the pivoted jointbetween the lower end of the connecting-rod and the treadle.

Letters of like name and kind refer to like parts in each of thefigures.

My invention is an improvement upon a similar device for which LettersPatent were granted me on the 29th day of August, 1871; and it consistsprincipally in the peculiar construction of the supporting and operatingdevices and their combination with each other and the table,substantially as and for the purpose hereinafter specified. It consists,further, in the means employed for securing in place the folding partswhen the same are closed together, substantially as hereinafter shown.

In the annexed drawing, A represents the table of a sewing-machine,supported by means of two legs, B and B, the upper ends of which areprovided with two hollow ears, b, that correspond to and receive thepintles of two lugs, D, which are secured to or upon the lower side ofsaid table, the whole being so arranged as to permit said legs to befolded inward upon each other. Pivoted upon or between two lugs, E,attached to and extending downward from the lower side and rear edge ofthe table A, is a brace, F, (having the form shown in Figs. 1 and 2,)the lower side of which is formed by a bar, f, that extends outward anddownward in the form of a curve and terminates at either end at theinner face and rear edge of the legs B and B. A set-screw, G, passeshorizontally into each end of the barf through a slotted lug, g, (opento the rear,) with its head upon the outer side of the latter, so thatwhen said screw is turned inward said lug shall be firmly claspedbetween said bar and screw-head and the brace and legs firmly united. Afurther support is given to the legs by means of a second brace, H,which is pivoted to or upon a lug, I, attached to the inner lower sideof the leg B, from whence said brace extends across and rests within aslotted ear, K, open at the upper side. A thread being provided upon theend of said brace, and a nut, 70, placed upon the same at each side ofthe lug K, the parts may be firmly united by turning inward upon eithernut. Suitably journaled upon the inner face of the leg B is an ordinaryband-wheel, L, for driving the operating mechanism of the machine, whichwheel is driven by means of a treadle, M, pivoted upon the brace H, andconnected with said wheel by means of a rod, N, the lower end of thelatter being loosely connected with an arm, m, that projects rearwardand outward from said treadle, while its upperend is pivoted to or uponsaid wheel in the usual manner. In order to permit the brace H to befolded upward the arm m of the treadle M is provided with a shortjournal, m, that is placed in line with the pivotal bearing of saidbrace, and has pivoted thereon a box, n, which moves freely around saidjournal or in a plane parallel to the line of said brace. The upper endof the box n is slotted in a line with the face of the driving-wheel,and within the slot thus formed is pivoted the lower end of the rod N,which is thus permittedto move freely in the necessary direction, thesame being a plane having a right angle to the line of the brace H.

The device is now ready for folding together, whichis accomplished inthe followingmanner: The braces being disconnected, the lower brace isturned against the leg B and said leg folded against the lower side ofthe table, after which the second leg B and the rear brace aresuccessively folded inward, as shown in Fig. 4. In order that the legsand rear brace may occupy their relative positions when closed the lugsof the leg B are shortest, those of the second leg somewhat longer, andthe lugs of the rear brace still further increased in length. Whenclosed the parts are locked in position by means of a set-screw, O, thatpasses horizontallyinward throughalug,P,thatis secured to and projectsdownward fiom the lower side the jonrn aled arm m, the connection N, andthe box 01, when the several parts are constructed as described andcombined with each other and with the table A, substantially as and forthe purpose specified.

2. Also, the pivoted brace F provided with the set-screws G, incombination with the hinged legs B and B and table A, substan- V tiallyas and for the purpose shown.

3. Also, in combination with the treadle M, provided with the journaledarm m and with the connection N, the box a, substantially as and for thepurpose set forth.

4. Also, the-lug P and setscrew O, in combination with the rear brace F,provided with v the projections F, substantially as and for the purposeshown and described.

In testimony that I claim the foregoing I have hereunto set my hand this11th day of December, 1871. I

AUSBERT H. WAGNER.
